To all whom it may concern Be it known that I, HENRY W; MIL ER, a citizen of theUnited States of America, residin at Brooklyn, in the county of Kings and 'tate of New York, have invented a new and useful Strainer, of which the following is a specification.

My invention relates to improvements 1n strainers .for vwater 1n SEPVICB OI' supply pipes, and consists of a certain peculiar chambered casing, which is adapted to be attached to water pipes, and is provided at the bottom with a removable plug or cap, and a foraminous mounted on a spindle that rises from said plug or cap, and supported said spindle in the water-way through sai casing, all as hereinafter set forth.

The object of my invention is to provide a comparatively simple and inexpensive .de-

vice for thoroughly straining foreign matter out of the water supply for ahouse or other building, and for catching such matter in such a manner th'at it can be removed easily and conveniently from time to time as may be necessary or desirable. This device can be readily installed at some suitable andconvenient point in the su l i e lineand after being so installed i io t be re moved under ordinary circumstances or conditions. 1 I

ther' objects and advantages will appear 1 in the course or the following description.

I attain the objects and secure the ad.- vantages of my mvention by the means illustrated in.- .the' accompanying. drawings, in

which I Figure 1- is a central vertical section through a strainer that embodies a practical form of; the invention; Figz- 2, a bottom'plan of the foraminous member or strainer proper, the spindle being. insection,

and, Fig. 3, a top plan of the cap, the spin'- dlezhere also being: in section. I Similar numerals refer to similar parts ithroughout the several views.

The device comprises a casing, 1,, an inverted cap 2 from the center of which rises a spindle 3, and a perforated cylinder' l which.

is mounted on the top ofsaid-spindlhr The cylinder 4 has a top 5 which is the part that is actually or directly mounted on the spindle 3, and said fpart may be rforated like the -pides o the -inverte cup formed by the cylinder 4 and said part or Specification of Letters Patent. 1

cylindrical member top. The center of the top 5 is attached to the spindle 3, and the latter thus passes through the axial center of the cylinderA. Preferably the aforesaid cup is formed from a sin 'le piece of foraminous material, al-

" thong this is not necessary, and the .cylinder 4 might be supported from the spindle '3'by some other means, as will be readily understood by one skilled in the art. Near the top of the casing 1 on one side 1s an. inlet connection 6 for attachment to a water pipe, and diametrically opposite suchconnection is an outlet connection 7 for attachment to a water pipe. It is by means of the connections 6 and 7 that the strainer is introduced into a line of supply pipes, the connection 6 being toward the source of supply so that the water enters the casing 1 through said connectionfi and leaves said casing by way of the connection 7 A cirou-- lar chamber 8 is formed in the upper; end of the,casing'1, into which the perforated clinder 4: is received, said chamberprefer a ly being larger'in diameter than is said cylinder. At the top of the chamber 8 is-an annular shoulder 9 into which the upper terminal of the cylinder 4:. is received and by which such terminalis. in part supported,

and at the bottom of said chamberis an annular flange 10, through which said cylinder passes when placed in operative position and removed from such position, and which in part supportstlielower terminal of said cylinder when in place. The construction of the upper portion of the caslng 1 1s such that water entering. said cas ng, through the Patented May 18,1915.

connection 6, must, in order to esca ,e 1

through theconnection 7 pass upwar y throu the flange 10 and the chamber 8, as wih'b'e clearly seen upon referring; to. Fig. 1'. Such being. the case, 1t follows that the wat'en must pass into the cylinder 4:, which fits within" the flange 10, and then out through into t e chamber 8, the water from said I chamher. assing onto the connection7. Any

and all orei'gn matter that may be present in the water,'upon its entrance to the casing theperforations in saidcylinder hand which is of such. a nature that it can not, pass through the perforations in the cylinder 4, is-cau'ght within the latter and directly or eventually falls or is washed down into a sediment chamber 11 in sa d casing.' Thus the supply of water between the strainer and the drawing point is freed from tent limited, only by the coarseness or fineness of the mesh of which the cylinder 4: .is

made orof the'perforations in said cylinder. The cylinder top 5 prevents the foreign. matter from escaping from the cylinder above and finding its way. down into the chamber 8.

The base of the spindle 3 is firmly set in the center of the cap 2, and said spindle rises from said cap through the sediment chamber 11. diameter'below the bottom horizontal plane ofthe connections 6 and 7, and the cap 2 is tapped into the open bottom of said -chamher, as represented at 12. The cap 2 is made hollow in order to increase the size of the sediment chamber or to add thereto, and to means.

making a tight joint between the cap-and with the twepositlonor the withdrawal of the same 4 casing, but may be changed altogether,

As occasion requires, the water is shut ofi between the connection 6 and the source of supply, and the cap'2 is unscrewed and removed, taking with it" the spindle 3 and the cylinder 4: or strainer proper. The accumulation of sediment in the chamber 13 is thus taken away, andthat in the chamber 11 falls out through the now open bottom of said chamber 11 or of the casing 1. The interior of the chamber 11 and the parts which have been removedare next thoroughly cleansed, and then said parts. are returned to place, the cap 2 being screwed tightly into the bot-" tom of the casing, as it was before. By employing for the strainer proper an open- 5 bottom cylinder which is uniform throughout, I provide an element'which is best calculated to free. itself from sediment and permits the water to flow without too muchinterference or retardation. The cylinder 4 should have a fairly tight fit with the flange 10 and the shoulder 9, but at the same time such fit; must not be so tight as to interfere placing, of said cylinder in operafrom such position.

In'additwn to some modifications hereinbefore noted, it is; to be understood that changes in the'shap'e and 'size' of my device eat an also 1n other' features. of air I foreign matter in suspension to an e'x- The chamber 11 increases in iaeeeeaconstruction of parts, may be made without de artingi from the spirit of my'invention.

hat claim as my invention, and desire to secure by Letters Patent,-is-- 1. The combination, in a device of the class described, with a casing having therein an open-bottom strainerchamber, and below said chamber an open bottom sediment chamber, and provided with oppositely-disposed'inlet and outlet connections, said inlet connection communicating with said strainer chamber through the bottom thereof by way of said sediment chamber, and said strainer chamber opening laterally into said outlet connection, of aremovable closure for the bottom of said'sediment chamber, a spindle fixed to said closure, and a perforated cylindrical member mounted on said spindle and receivable in said strainer chamber, with the base of said member fitting the bot tom opening in said strainer chamber, said spindle. with said closure being the sole axial support "for said member, and the arrangement of parts, being such that said spindle and member come away with said closure,

and said' member is returned to place by the act of replacing said closure.

of said s'edimentchaniber, and said" strainer chamber opening laterally into sald outlet connections, of a removable closure for the bottom of said sediment chamber, a vertical spindle rising from said closure and having its base permanently attached thereto, and a perforated cylindrical member provided with a .top mounted on said spindle, the lattar passing through the axial center of said member and with said closure serving as the sole sup ort for said member, and said member b lrifg receivable in said strainer chamber, with the base ofsaid member fitting the bottom opening in said chamber,

the arrangement of 'parts being such that said spin le and member come away with said closure, and said member is returned to place by the .act which replaces said losure.
